Aaron Arellano · Answer 1

Technician B is correct. The voltmeter should be connected in parallel with the circuit that is being tested.

Explanation:

This is because the potential difference, that is being measured by the voltmeter, is always across the end of the conductor or the resistor (s) according to Ohm's law of electricity.
